Navigating the procurement of specialized chemical compounds is a critical task for professionals in the pharmaceutical and chemical industries. Fendizoic acid (CAS 84627-04-3) is one such compound, recognized for its specific applications and the importance of its quality. This article provides an overview of Fendizoic acid's key specifications, its primary uses, and essential considerations for sourcing this vital intermediate. As a dedicated pharmaceutical intermediate supplier, we aim to provide clarity and support for your procurement needs.

Fendizoic acid is chemically known as 2-[(6-Hydroxy[1,1'-biphenyl]-3-yl)carbonyl]benzoic acid. Its molecular formula is C20H14O4, and it has a molecular weight of 318.32 g/mol. In terms of physical characteristics, it is typically presented as a light yellow to almost white powder. The most critical specification for its use in pharmaceutical manufacturing is its assay, which is reliably maintained at ≥99.0%. This high purity is essential to prevent unwanted side reactions and ensure the quality of the final drug product.

The primary utility of Fendizoic acid lies in its role as a pharmaceutical intermediate and, notably, as a counterion. It is a key component in the formation of cloperastine fendizoate, a widely used antitussive medication. In this context, Fendizoic acid is reacted with the active pharmaceutical ingredient cloperastine to form a salt. This salt formation process can influence the physicochemical properties of the drug, potentially improving its solubility, stability, and pharmacokinetic profile, thereby enhancing its therapeutic efficacy.

For companies engaged in the production of cloperastine fendizoate or other drugs requiring Fendizoic acid, securing a consistent and reliable supply is paramount. When looking to buy Fendizoic acid 84627-04-3, it is crucial to partner with reputable suppliers. Understanding the specifications, such as assay, appearance, and the presence of any specified impurities, is the first step. Obtaining a detailed Fendizoic acid price quote from a trusted manufacturer is also important for budgeting and cost management.

The global market offers numerous sources for Fendizoic acid, with many manufacturers based in China. These producers often provide competitive pricing due to advanced manufacturing infrastructure and economies of scale. However, it is advisable to conduct due diligence when selecting a supplier. Verifying their quality control measures, regulatory compliance, and ability to provide comprehensive product documentation, such as Certificates of Analysis (CoA), will ensure you receive material that meets the stringent requirements of pharmaceutical production.

In summary, Fendizoic acid is a critical pharmaceutical intermediate with defined specifications and essential applications, particularly in the formulation of antitussive drugs. Its high purity is a non-negotiable aspect for pharmaceutical manufacturing. By carefully considering product specifications and engaging with reliable manufacturers and suppliers, companies can ensure a stable and high-quality supply of Fendizoic acid, supporting the efficient and safe production of essential medicines.
